Building Better Businesses Together

Following Future of Energy Day, join us as we celebrate 18 years of Colorado Cleantech! For nearly two decades, Colorado Cleantech has worked to connect innovators, industry leaders, investors and partners to help grow Colorado's cleantech ecosystem. We're excited to celebrate how far this community has come — and look ahead to what's next. As part of the celebration, we'll officially launch Colorado Cleantech Dealroom, a new platform designed to increase visibility and connectivity across Colorado's cleantech ecosystem. Dealroom will make it easier to discover Colorado companies, technologies, investors and organizations and create new connections across the community. Then, stick around for happy hour and networking as we celebrate 18 years of Colorado Cleantech and the founders, partners, members and community that have made it possible. This event is free and open to the cleantech community. Come celebrate 18 years with us — and help us kick off the next chapter of Colorado Cleantech.

We're back in Denver for the September 2026 AI Builders Meetup, kicking off the fall series at Colorado Startup Week! As always, this event is free and open to all. With food and beverages thanks to our awesome sponsors. 🙌 Come see what people are building in Colorado and meet other builders. Doors at 5 pm Content starts at 5:45 pm Building something? Tell us in the RSVP. We always get more demo asks than we have slots, and we prioritize the ones people will want to see. We're deeply grateful to our partners at NVIDIA, Silicon Valley Bank, and Venture X Denver LoDo for supporting these events, and to our co-organizers at Ombud and Matchstick Ventures.

AI coding has fundamentally changed how software is written and improvements are real. Tools like Claude Code and Cursor speed up developer velocity and change how we approach software engineering. However, as AI is writing more code than ever, testing and verification are the new bottlenecks. Join Antithesis for a curated evening with engineers, development and infrastructure leaders exploring how teams can build resilient distributed systems while adopting faster, more autonomous software development workflows. As AI-assisted and agent-generated code accelerate the pace of change, correctness and resilience can no longer be left to conventional testing alone. These events will bring together practitioners to discuss how leading teams are approaching failure testing, distributed systems reliability, observability, and pre-production validation. Schedule for the event: 6:00 - 6:30pm: Drinks, Food, and Networking. 6:30 - 7:30pm: Building Resilient Systems Presentation led by Antithesis' very own Adrian Hatch! 7:30pm - til close: Bowling, Games, and fun. Are you and your team stretched thin because you are dealing with more and larger PRs, and spend most of your time doing code reviews? Are your agents writing tests that mostly cover the obvious path, but fail to find the real bugs affecting your customers? Are you and your team still hunting for subtle, hard-to-find bugs despite the use of AI? If you are looking to increase your productivity and want a more rigorous approach to finding, reproducing, and fixing bugs that slip past conventional testing, we would love to have you join us.
